• on chromosomes

• on an organism

Multiple Choice

Survival of the Fittest and Evolution were proposed by what scientist?

• Charles Darwin
• Albert Einstein
• Steven Hawking
• Isaac Newton

Multiple Choice

Where the better adapted organisms survive to pass traits along to offspring.

• Evolution
• Natural Selection
• Extinction
• Artifical Selection

Multiple Choice

Why are advantageous traits more likely to be passed onto offspring?

• Because they are more likely to survive and reproduce.
• Because they come from dominant alleles.
• Because they come from recessive alleles.
• Because the trait is an acquired phenotype.

Multiple Choice

Do organisms "decide" to evolve and change?

• Yes, they know they need to change to survive 
• No, they change because of natural selection

Multiple Choice

Why is the mouse population changing over time?

• The light mice can reproduce more successfully than the dark mice
• The hawks eat more dark mice than light mice because the dark mice taste better
• The hawks eat more light mice than dark mice because they can see the light mice more easily
• The hawks eat more dark mice than light mice because they can see the dark mice more easily

Multiple Choice

Mutations are important because they bring about

• death of the organism in which they develop

• genetic variation needed for a population to evolve

• benefits for the individual, not for the population

• changes in genotype, but not phenotype

Multiple Choice

Why do frogs and other organism reproduce so many eggs or offspring?

• so that their babies can have friends to play with
• the more offspring the more likely the offspring will survive
• the more offspring the less likely offspring will survive 
• the more offspring the less competition

Multiple Choice

Which organisms are most likely to survive?

• the best adapted
• the fastest
• the strongest
• the most domesticated (tamed)

Multiple Choice

The long and sharp beak of a woodpecker is an example of:

• Natural Selection
• Selective Breeding

Multiple Choice

Domesticated dogs are an example of:

• Natural Selection
• Selective Breeding

Multiple Choice

Why is competition important for natural selection?

• It shows which variations are more successful, allowing the organisms with those variations to survive.

• It causes organisms, regardless of which traits they have, to die out, reducing the population size.

• It causes organisms to get stronger due to having to outcompete other species.

• Competition is not important for natural selection.

Multiple Choice

If an organism can't adapt fast enough, this might happen.

• hibernate
• stay the same
• live longer
• become extinct

Multiple Choice

Darwin said that within a species there will be _________________________

• nothing different
• variation/differences

Homologous Structures

Organs or skeletal elements of animals and organisms, that due to their similarity, suggest a connection to a common ancestor. This is important because scientists can use this as evidence of evolution.

Multiple Choice

What is the most important aspect of homologous structures?

Superposition

The Law of Superposition: The younger layers of rock are on top of the older layers of rock.

Multiple Choice
